Driverless cars and planes are no longer the stuff of the future. In the city of San Francisco alone, two taxi companies have collectively logged 8 million miles of autonomous driving through August 2023. And more than 850,000 autonomous aerial vehicles, or drones, are registered in the United States—not counting those owned by the military.

But there are legitimate concerns about safety. For example, in a 10-month period that ended in May 2022, the National Highway Traffic Safety Administration reported nearly 400 crashes involving automobiles using some form of autonomous control. Six people died as a result of these accidents, and five were seriously injured.

The usual way of addressing this issue—sometimes called "testing by exhaustion"—involves testing these systems until you're satisfied if they're safe. But you can never be sure that this process will uncover all potential flaws. "People carry out tests until they've exhausted their resources and patience," said Sayan Mitra, a computer scientist at the University of Illinois, Urbana-Champaign. Testing alone, however, cannot provide guarantees.
